I have this engine on an 18 foot bass boat. My wife does not like to go 50 or 60 mph so when we were out this weekend I was dogging it, going pretty slow. Suddenly the mighty engine quit. Chug chug gasp. I got it started and throttled up to crusing speed and it ran good the rest of the weekend. Could it be that running so slow for so long fouled the plugs?
